SPECIFICATION forming part of Letters Patent No. 723,337, dated March 24, 1903. Application iiled August 14, 1902. SerialNo. 119,596. @lo model.)

To all whom it may concern:

Be it known that I, EDMOND THOMINE, a citizen of the Republic of France, residing atp-No. l Rue de 1a Chausse dAntin, in the city of Paris, Republic of France, have invented certain new and useful Improvements in Steam- Generators, of which the following is a speciication, reference beingV had therein to the accompanying drawings.`

. This invention relates to steam-generators,

and is adapted for use With generators wherein the steam supply is intermittent, as in sugar-refineries, steel-works, mines, &c.- In

y steam without requiring a fresh supply of the type of generator at present in use for such and similar purposes large water-space has been provided to insure safety, particularly in instances wherein the Water and steam space is exposed to the directaction ot theV furnace-gases.

The present invention consists in provid-V cold feed-waterh In the accompanying drawings, forming a .partof this specificationptheinvention is illustrated in connection with the usualsteam and Water drums located' above the generator, two of such drums being represented with"` an auxiliary drumjor accumulator embodyh ing the present invention;-

Figure l'represents a front View, and Fig.

` 4 23a sectional side View, showing the pipe and valve connections.

`1 and 2 are the usual steam and Water drums, and 3 the accumulator-drum. The respective y drums l, 2, and 3 are in free communication `by means of the pipes A, connecting at the top of each, as shown, and with the4 pipe B depending from the topof `the accumulatordrum through its interior and' connected to,

` the horizontal perforated drum C. The pipes A receive the steam from the generator-drums l and 2 and convey it to the Water-space in the accumulator 3` through the pipe B and perforated drum G.. AThe stearntherefore passesthrough the connections described from the beginning of its formation and during the whole period of generation, and the Water in the accumulator is thereby maintained at the temperature of the Water in the generator. The steam-outlet is represented at -V, Fig. 2, at the top of the accumulatordrum. The steam being taken for use from the accumulator and free from the vessel in which it is generated is comparatively dry.

The feed-Water connections are arranged to feed atwill directly into the generatordrums l and 2 through the Vadmission-valve R, pipe D,checkvalves E,`.and pipes F, or through the admission valve R', pipe D', check-valve E', and pipe T into the accumulator-drum 3, and from the latter into the drums l'and 2 through valve r, pipes d, and pipe t, or' through both simultaneously. The elevated valve lr is adapted to`be operated from the reroom by means of the connected Wheel and chain s. The respective drums are shown filled to the normal level indicated by the valve-gages placed on the front of the drums, as shown in Fig. l. When 'the motor or apparatus using the steam is started, the valves R, R, and r may be closed and no fresh feed admitted so long as the water-level in the drums l and 2 is above the lowest level permitted. At this point the feed is admitted through the valve r from the accumulatingdrum 3 and-continued until its complete eX- haustiontherefrom or down to a level adopt- ;*ed by-.thelocation of the valve r;

Injig.` 2 a partition k is shown in the ac- `cumulator-drum extending vertically to the level 'of the valve r and between "the feed- `outletvalve r inside the feed-pipe T to arrest the deposit of substances and salts entering through the pipe T or forming in the accumulator by reason of the equal temperature of-the water with the `temperature of the steam. With this partition theaccumulator serves as a purifier, the `precipitated salts settling in the pocket and remaining there `.without danger of adhering, as the accumulator is not exposed to the action of the fur- The size of the generator-drums and theaccumulator can be varied to make the Waterreserve as large as the requirements call for, and the invention may be adapted for use with any type of generator. l It holds a large IOO reserve of Water raised to the temperature of the steam itself and is not exposed to the action of the furnace-gases, and therefore not liable t0 explode, and at the same time serves to purify the feed-Water.

Having thus fully described the invention, What is claimed is- In combination With a steam-generator of an elevated accumulator-drum provided With the pipe A in open communication with the steam-space of the generator; a pipe B communicating with the pipe A and the waterspace of the accumulator, an independent feed-Water inlet and a feed-Water outlet communicating with the Water-space of the generator as set forth. l

In testimony whereof I afx my signature in presence of two Witnesses.
